version: 1.0.167

Supersedes the inline-structural approach (0d282cc): inlining erased the value
type's name, so identical nested shapes (weekly_hours at two paths) generated
duplicate leaf types downstream and Dart barrel exports collided. Now a named
non-table value type's filter is synthesized ONCE (like table-backed boundaries)
and property references point at it — mirroring how the entity side generates
one class per named type. Same filter-by-fields capability; laziness also
removes the structural-recursion hazard. A named type with no compilable
structure still gets no filter and is omitted rather than dangled.
